Im doing my first KiCad project, and I want to make through holes so the components are mounted on the front side and the copper of the through hole is only on the back side (because my manufacture dont do "vias through-holes"). Do I accomplish this by (was supposed to post a image here but stackoverflow do not allow me to):

  1. From Pad Properties under "Layers" section, choose Copper to "B.Cu" instead of default "all copper layers".

or 2: do I have to set Pad Type to NPTH and do the same as in 1?

thanks for any replies :)

I suspect that your fab house misunderstands your request or you have an error in your board (maybe you have a via that is located inside your throughhole?)

That said, if you really want to accomplish this, then option 1 is your correct method.

  • maybe Im the one who misunderstands? (english is my second language). This is what they write: "All tracks going to headers or hole-mounted components must connect from the opposite to the side where you place the component or header. This is because the holes for the components are not normally metallized, so there is no connection between top-and bottom side. If you still need to place tracks on the same side as the component, you must start routing from the bottom side, then place a dedicated via to be able to continue routing on the top layer." – hoddy Mar 20 '18 at 09:35
  • I understand. They are saying that they do not plate the connections. You don't need to adjust your pcb. Just make sure that your tracks connect to bottom layer (so that you can solder correctly). You can have the pad on the top layer as well but there isn't an electrical connection in the pad between the top and bottom. – Seth Mar 20 '18 at 16:42
  • That said, this is _very_ unusual. I hope that the fab house is giving you a really good price. – Seth Mar 20 '18 at 16:44
  • Im getting it for free, so can't complain ;) Thanks for help! – hoddy Mar 21 '18 at 09:17
